ASAP plaase ABCD is a square. The length of each side of the square ABCD is___units, and the length of its diagonal is about_units. First options:9, 14, 28 Second options:14, 18.6, 19.8

length is 14

diagonal is 19.8

Step-by-step explanation:

To find the length of the side of the square, what we need to do is to use the height 12 in each triangle to find the length of the adjacent in each triangle and add together.

Mathematically we can find the length of this adjacent using the Pythagoras theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides.

Applying this to each of the 2 triangles but summing the answer;

The length l is as follows;

Let’s call the adjacent fir each side of the triangle a and b but the addition being l

a^2 = 15^2 - 12^2 = 225-144 = 81

a^2 = 81

a = 9

b^2 = 13^2 -12^2

b^2 = 169-144

b^2 = 25

b = 5

l = a + b = 9 + 5 = 14

The diagonal can also be calculated using pythagoras’

d^2 = 14^2 + 14^2

d^2= 196 + 196

d^2 = 392

d = √(392)

d = 14√2 = 19.8

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
